Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective is to assess the effect of 2 dose levels of SNF472 (300 mg and 600 mg) compared to placebo on the progression of coronary artery calcium volume score over a 12-month (52 weeks) period in ESRD patients on HD

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Reducing the progression of cardiovascular calcification (CVC) in HD patients may improve the severe burden of CV disease related to the underlying ESRD. As no therapy is currently indicated to target CVC, there is a need to investigate the ability of SNF472 to reduce CVC progression and, ultimately, to improve CV outcomes in HD patients. This phase 2b double-blind, randomised, placebo-controlled study is designed to assess the effect of SNF472 on the progression of CVC as measured by calcium volume and CAC/Agatston scores in ESRD patients receiving HD. The study hypothesis is that administration of SNF472 over 52 weeks can slow the progression of CVC in this patient population compared to placebo.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Female or male patients, 18 to 80 years (inclusive) of age at randomisation
* CAC score of 100 to 3500 AU (Agatston Units) inclusive within a 3-week period prior to randomisation as measured by a multi-detector CT scanner
* Patients who are EITHER ≥ 55 years OR have a history of diabetes mellitus at randomisation
* Patients on HD for ≥ 6 months prior to randomisation
* Willing and able to understand and sign the informed consent

Exclusion Criteria

* Scheduled date for kidney transplant from a known living donor
* Weight above 300 lbs (136 kg)
* Hospitalisation in the previous 3 months prior to randomisation for unstable angina, MI, stroke, transient ischaemic attack, amputation or peripheral or coronary bypass surgery
* History of unstable heart failure in the previous 3 months, defined as an unplanned presentation to a hospital or dialysis treatment facility with signs/symptoms of acute pulmonary edema and requiring ultrafiltration therapy
* History of cancer that has been in remission for \< 5 years prior to randomisation. A history of basal cell carcinoma or Stage 1 squamous cell carcinoma of the skin is allowed
* Pregnant or trying to become pregnant, currently breast-feeding, or of child-bearing potential (including peri-menopausal women who have had a menstrual period within one year) and not willing to practice birth control using a double barrier method (criteria apply to women only) at least 30 days post last dose of study medication
* Hypocalcaemia defined as a serum calcium below 8.0 mg/dL (or 2.0 mmol/L) for the serum calcium most proximal to screening per patient's medical records
* Extreme elevation in serum phosphorous, defined as a serum phosphorous above 10 mg/dL (or 3.23 mmol/L) within the last 2 months proximal to screening per patient's medical records
* Uncontrolled hypertension defined as any 2 or more consecutive post-dialysis diastolic blood pressure (DBP) \> 100 mmHg within the last 2 months proximal to screening expected survival \< 2 years in the Investigator's medical opinion
* Known active drug or alcohol abuse within 1 year of randomisation
* Use of other investigational drugs within 30 days of randomisation
* Non-compliance with dialysis treatment which, in the opinion of the Investigator, evidenced by either repeated missed dialysis treatments or significant non-compliance with the patient's medication regimen
* Inability to comply with all required study procedures and schedule, inability to speak and read in the protocol-derived language of that patient's clinical site, or unwillingness or inability to give written informed consent
